Owner’s Manual for Stationary Emergency Generators 29
5.3 — Service Maintenance Intervals
NOTE: Use only Genuine Generac parts to ensure warranty coverage.
All generator service must be performed by an authorized service provider or a qualified service person-
nel only.
It is important to perform all maintenance at the interval specified in the Service Maintenance Schedule. This ensures
safe and proper operation, as well as compliance with applicable emissions standards. Critical emissions maintenance
must be performed for the Emissions Warranty to remain valid. Service and repairs may be performed by an authorized
service provider, any qualified service technician, or repair shop.
Observe the maintenance tasks and intervals shown in the table below.
NOTE: If the unit reaches a Schedule A or Schedule B maintenance interval with 900 to 999 total hours, have
an authorized service provider perform the Schedule C maintenance tasks as well (and reset the A-B-C/Year
maintenance schedule counter).
